Abstract
Early interstitial fibrosis (IF) correlates with long-term renal graft dysfunction, highlighting the need for accurate quantification of IF. However, the currently used Banff classification exhibits some limitations. The aim of our study was to precisely describe the progression of IF after renal transplantation using a new morphometric image analysis method relying of Sirius Red staining. The morphometric analysis we developed showed high inter-observer and intra-observer reproducibility, with ICC [95% IC] of respectively 0.75 [0.67–0.81] (n = 151) and 0.88 [0.72–0.95] (n = 21). We used this method to assess IF (mIF) during the first year after the kidney transplantation from 66 uncontrolled donors after circulatory death (uDCD). Both mIF and interstitial fibrosis (ci) according to the Banff classification significantly increased the first three months after transplantation. From M3 to M12, mIF significantly increased whereas Banff classification failed to highlight increase of ci. Moreover, mIF at M12 (p = 0.005) correlated with mean time to graft function recovery and was significantly associated with increase of creatininemia at M12 and at last follow-up. To conclude, the new morphometric image analysis method we developed, using a routine and cheap staining, may provide valuable tool to assess IF and thus to evaluate new sources of grafts.

Abstract
BACKGROUND Uncontrolled non-heart-beating donor (UNHBD) transplantation offers a major opportunity to ameliorate the effects of the donor shortage. However, little is known about the true status of the organs obtained from these donors. UNHBD transplantation is performed under unfavorable conditions and involves exposure to several harmful stimuli that have been identified as triggers for immediate inflammatory response, oxidative stress, and apoptotic phenomena. This adverse scenario could explain the higher rates of graft dysfunction due to primary nonfunction traditionally observed in NHBD. Our aim was to assess the expression of proinflammatory, oxidative, and apoptotic markers in liver, lung, and pancreas tissue samples obtained from UNHBD and to compare these expression levels with those observed in brain-dead donors (BDD). METHODS Samples from human type 2 NHBD and BDD were obtained at the end of cold storage. Interleukin (IL)-1β, tumor necrosis factor-α, IL-6, IL-10, endothelial nitric oxide synthase, inducible nitric oxide synthase, type 1 heme oxygenase, type 2 heme oxygenase, Bax, and Bcl-2 protein and mRNA expression, as well as catalase, glutathione peroxidase, and glutathione reductase tissue activity, were determined. RESULTS UNHBD showed similar or lower expression of proinflammatory mediators and apoptosis markers in all three organs without modifications to the anti-inflammatory cytokines. Although the major oxidative stress marker levels were also comparable in both types of donors, the type 1 heme oxygenase mRNA expression and antioxidant enzyme activity were slightly diminished in UNHBD. CONCLUSIONS The initial tissue damage generated during the UNHB donation process is at least comparable with that observed in BDD. However, although the expression of the immediate immune response and apoptosis markers is similar, a mild impairment of the local antioxidant activity was observed.

Abstract
There is continuing disparity between demand for and supply of kidneys for transplantation. This review describes the current state of kidney donation after cardiac death (DCD) and provides recommendations for a way forward. The conversion rate for potential DCD donors varies from 40%-80%. Compared to controlled DCD, uncontrolled DCD is more labour intensive, has a lower conversion rate and a higher discard rate. The super-rapid laparotomy technique involving direct aortic cannulation is preferred over in situ perfusion in controlled DCD donation and is associated with lower kidney discard rates, shorter warm ischaemia times and higher graft survival rates. DCD kidneys showed a 5.73-fold increase in the incidence of delayed graft function (DGF) and a higher primary non function rate compared to donation after brain death kidneys, but the long term graft function is equivalent between the two. The cold ischaemia time is a controllable factor that significantly influences the outcome of allografts, for example, limiting it to < 12 h markedly reduces DGF. DCD kidneys from donors < 50 function like standard criteria kidneys and should be viewed as such. As the majority of DCD kidneys are from controlled donation, incorporation of uncontrolled donation will expand the donor pool. Efforts to maximise the supply of kidneys from DCD include: implementing organ recovery from emergency department setting; improving family consent rate; utilising technological developments to optimise organs either prior to recovery from donors or during storage; improving organ allocation to ensure best utility; and improving viability testing to reduce primary non function.

Abstract
AIM To evaluate the rate of organ donation after brain death in 2 tertiary care medical centers of a Romanian city, the reasons for donation exclusion (donors or organs), and identification of potential strategies for improvement. MATERIAL AND METHODS The study retrospectively evaluated potential organ donors with brain death (BD) who were identified between January 2006 and June 2009 in an university city of Romania. The potential donors were considered patients with severe intracranial pathology and clinical signs of brain death who were reported to the regional transplant team. The BD declaration was completed according to the Law of Transplant Procurement and Management in Romania: clinical signs of brain stem death, apnea test, and flat EEG, criteria that must be fulfilled twice at a 6 hour interval. According to Romanian law, family consent is mandatory for organ harvesting. RESULTS The study included 35 potential donors, of whom 22 had a declaration of BD. Failure of potential donors to be declared BD was caused by positive viral serology (n = 7), improvement in clinical status (n = 2), sudden cardiac arrest (n = 2), and refusal of physician in charge (n = 2). Among the 22 with a BD declaration, organ harvesting was performed in only 12 cases due to family refusal (n = 10). In 4 cases the planned organ harvesting was aborted owing to unexpected intraoperative findings. DISCUSSION Factors that generate the low rate of organ procurement include local organizational particularities, a high rate of viral infections, poor education, (both of lay persons and of medical personnel), restrictive criteria for BD declaration and the mandatory need for family approval. CONCLUSION The rate of donation in this university city of Romania is still low. Several strategies have been identified to improve the rate: better identification of potential donors, better management, and education of the public and of health care personnel.

Abstract
INTRODUCTION AND GOALS Renal procurement after a period of heart st op demands a previous knowledge of ischemia-reperfusion injuries means. To study cell injury mechanisms an experimental study has been designed in pigs, with different rangres of warm ischemia (0-30-45 and 90 min). The main goal was to research on the basis of ischemic injury. MATERIAL AND METHODS Biochemical parameters (creatinine, urine output), energetic loading (ATP, ADP, AMP and global energetic loading) and pathological studies as long as survival analysis by 5th day were completed. RESULTS Animal survival and graft viability range from 100% at 5th day in control and 30 min warm ischemia groups to 60% in 90 min warm ischemia group. Creatinine levels rises at 1st, 3rd and 5th day, especially in those non-viable organs. ATP levels decrease after warm ischemia period, increases ADP and AMP levels after reperfusion in those viable organs. CONCLUSIONS Prolonged periods of warm ischemia do not result necessarily in non-viable kidneys. Viable organs recover nucleotide levels early. Study of energetic cell loading levels is a good way to get on better in the knowledge of injury mechanisms after ischemia-reperfusion.

Abstract
During the past 50 years since the first successful organ transplant, waiting lists of potential organ recipients have expanded exponentially as supply and demand have been on a collision course. The recovery of organs from patients with circulatory determination of death is one of several effective alternative approaches recommended to reduce the supply-and-demand gap. However, renewed debate ensues regarding the ethical management of the overarching risks, pressures, challenges and conflicts of interest inherent in organ retrieval after circulatory determination of death. In this article, the author claims that through the engagement of a Heideggerean existential phenomenological and hermeneutic framework what are perceived as ethical problems dissolve, including collapse of commitment to the dead donor rule. The author argues for a revisioned socially constructed conceptual and philosophical responsibility of humankind to recognize the limits of bodily finitude, to responsibly use the capacity of the transplantable organs, and to grant enhanced or renewed existence to one with diminished or life-limited capacity; thereby making the locus of ethical concern the donor-recipient as unitary ''life.'' What ethically matters in the life-cycle (life-world) of donor-recipient is the viability of the organs transplanted; thereby granting reverence to all life.

Abstract
AIM: To investigate the histological and ultra-structural characteristics of liver graft during different of warm ischemia time (WIT) in rats and to predict the maximum limitation of liver graft to warm ischemia.
METHODS: The rats were randomized into 7 groups undergoing warm ischemia injury for 0, 10, 15, 20, 30, 45 and 60 min, respectively. All specimens having undergone warm ischemia injury were investigated dynamically by light and electron microscopy, and histochemistry staining. After orthotopic liver transplantation (OLT),the recovery of morphology of liver grafts after 6, 24 and 48 h was observed.
RESULTS: The donor liver from non-heart-beating donors (NHBD) underwent ischemia injury both in the warm ischemia period and in the reperfusion period. Morphological changes were positively related to warm ischemia injury in a time-dependent manner during the reperfusion period. The results demonstrated that different degrees of histocyte degeneration were observed when WIT was within 30 min, and became more severe with the prolongation of WIT, no obvious hepatocyte necrosis was noted in any specimen. In the group undergoing warm ischemia injury for 45 min, small focal necrosis occurred in the central area of hepatic lobule first. In the group undergoing warm ischemia injury for 60 min, patchy or diffused necrosis was observed and the area was gradually extended, while hepatic sinusoid endothelial cells were obviously swollen. Hepatic sinusoid was obstructed and microcirculation was in disorder.
CONCLUSION: The rat liver graft undergoing warm ischemia injury is in the reversible stage when the WIT is within 30 min. The 45 min WIT may be a critical point of rat liver graft to endure warm ischemia injury. When the WIT is over 60 min, the damage is irreversible.

Abstract
The chronic shortage of deceased kidney donors has led to increased utilization of donation after cardiac death (DCD) kidneys, the majority of which are procured in a controlled setting. The objective of this study is to evaluate transplantation outcomes from uncontrolled DCD (uDCD) donors and evaluate their utility as a source of donor kidneys. From January 1995 to December 2004, 75,865 kidney-alone transplants from donation after brain death (DBD) donors and 2136 transplants from DCD donors were reported to the United Network for Organ Sharing. Among the DCD transplants, 1814 were from controlled and 216 from uncontrolled DCD donors. The log-rank test was used to compare survival curves. The incidence of delayed graft function in controlled DCD (cDCD) was 42% and in uDCD kidneys was 51%, compared to only 24% in kidneys from DBD donors (p < 0.001). The overall graft and patient survival of DCD donors was similar to that of DBD donor kidneys (p = 0.66; p = 0.88). Despite longer donor warm and cold ischemic times, overall graft and patient survival of uDCD donors was comparable to that of cDCD donors (p = 0.65, p = 0.99). Concerted efforts should be focused on procurement of uDCD donors, which can provide another source of quality deceased donor kidneys.

Abstract
Procurement of kidneys and livers from non-heart-beating donors (NHBD) raises ethical and legal issues that need to be considered before wider use of these donors is undertaken. Although NHBDs were used in kidney transplantation as early as the 1960s, retrieval of these organs is not universally accepted today. From a medical point of view, these organs were considered "marginal" because the majority showed delayed or impaired function early after implantation. Legal problems relate to determination of death on cardiopulmonary criteria, the issue of valid consent, and the use of preservation measures. Among ethical issues involved are observance of the dead-donor rule, decisions with respect to resuscitation and withdrawal of life-sustaining treatment, respect for the dying patient and the dead body, and proper guidance of the family. In The Netherlands NHB donation was pioneered by the Maastricht Centre as early as 1981. Today, all seven transplant centers procure and transplant these organs, and NHBDs have become an important source of transplantable kidneys and livers. Recent legislation in The Netherlands also supports NHB donation by allowing the use of organ-preserving measures, even in the absence of family consent. As a result, one of every three kidneys transplanted in The Netherlands in 2004 derives from a NHBD. This article explores Dutch NHBD practice, protocols, and results and compares these data internationally.
